WILFRED J. RoY. or EAST ORANGE, NEW JERsEx-AssIeNoRro GEMEX'COMPA'NY, or NEWARK, NEW JERSEY, A CORPORATION on NRw ERsRY BRACELET CHAIN Application filed August 20, 1928. Serial No. 300,784.

This invention relates to an improved construction of braceletor chain formed of a plurality of units flexibly connected together; and the object of this inventionis to provide a construction of bracelet or chain having a series of units which maybe'disconnect'ed bya yielding movement of a resilient- I 1y, mounted member or pin. 7 A further object of the invention is the provision of means for retaining the pin in withdrawn position to permit disconnection ofthe links one from the other.

vA. further object of the invention is the mounting of a separable member having a resiliently mounted pin in position to extend thru registering openings in the overlapping end portions of adjacent bracelet units.

' The'invention further consists in the provision of a guide in the connecting member to assist in positioning the pin so that it may always move outward thru the opening provided under "influence'of its spring.

H With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. In the accompanying drawings: V

V Fig. 1 is a top plan view of a series of units 9 connected together.

Fig. 2 is a side elevation thereof. 7 Fig. 3 is a sectional view on line 33 of Fig. 2 illustrating the units as connected together by my. improved construction.

7 Fig. 4 is a view similar to Fig. 3 showing the pin'in withdrawn position.

Fig. 5 is a sectional view on l1ne of Fig. 2 with the pin in its connecting position. Fig. 6 is ayiew similar to Fig. 5 w1th the pin in withdrawn position.

Fig. 7 shows the pin in one of the links withdrawn and the'other link as being moved to disconnect the same therefrom.

Fig. 8 is a sectional. view on line 8-8 of Fig. 1.

Fig. 9 is a perspective view partially broken away illustrating the 'slot and notch as formed 1n the shell for housing the resillently mounted pin.

' Fig. 10 is a sectional view showing a separate connecting member.

Fig. 11 shows the separate member of Fig.

10 as mounted in position in one of the units. Fig. 12 is a perspective view partially broken away showing the, connecting member as applied to an extendible bracelet.

" Fig. 13 is a sectional View of another con struction of a separate connecting member. In the practical construction and operation of bracelets, it is found desirableto detachably connect the units ofthe bracelet one tot-he other so thatby manual manipulation with some such simple tool as a common ordinary pin or the like these units may be disconnected one from'the other to replace a broken link or to shorten or enlarge the lengtl'i of the bracelet to accommodate the same to diiferent sized wrists of wearers and in order to accomplish this result-I have provided a connecting member with a resiliently mounted pin which may bemoved to permit disconnection of the units of the bracelet one fromthe other as desired; and'the following is a detailed descriptionof the present em-' bodiment of this invention showing the preferred. means-by which these advantageous results maybe accomplished.

-With reference tothe drawings, 10 designates the link units which are-provided at their ends withears 11 and 12 to overlap each other and receive thru their registering openings 13 and 14 a pin 15 of theconnecting member. V

This connecting member may be formed as a separate unit removable from the link, as illustrated in Fig. 10, or, the stock of the top wall of the unit may be extended as at16, illustrated in Fig. 8, to form the shell designated 17 in Fig. Sand 18 in Fig. 10, to house the pin 15. I I 1 In the construction illustrated in Fig. '10,-
